Next up is the model the "Hurst Hairy Olds" I realy wanted to use but at 1/24th scale I think it's just to long of a wheelbase. At just about 5 inches the only way I could do it is to use a little drive shaft extion and I'm not a big fan of that but I think I came up with a solution that might just work.

With such unusual cars, I think it's about way more than *just* sheer performance (although 2 Kemtrons ought to provide a LOT of torque!). I think it has a lot to do with elegance and engineering "period" solutions, and yours has plenty of both. That's why I'm very interested in all this and to see what Joe Mig comes up with.

Since Drag cars don't require the normal weight placement, I would push that monster motor as far forward as possible and use an extension shaft at the rear. That way you might be able to get away without using wheelie bars. ( I think they ruin the scale aspect of these builds)

Also, since the car doesn't go around corners, maybe try moving that guide back behind the front bumper.

I have been thinking about building a drag car myself. Even built one stock just so I could "bench race" other ideas.

As for a two-motor Hurst Hairy Olds.... I got one started myself too!

Well, it's not duel motored yet. The idea was to write an article about modifying the newer AMT chassis with a 1966 Olds body mounted on top.
First stage is finish the body and race the stock chassis with an average drag race time.
Then start modifying until ultimately two chassis are soldered together to provide two motor brackets.

I would push that monster motor as far forward as possible and use an extension shaft at the rear. That way you might be able to get away without using wheelie bars. ( I think they ruin the scale aspect of these builds).

Thats what i have in mind and did some mock up using the motor mount from a sprint car chassis up in front.
putting the weight up front and a drive shaft to a rear motot mount.

Nice build by the way and I think most of us building this car feel the same about no wheelbars.
Now all I need is one of those littli Linder V.

Some people are like Slinkies... they're really good for nothing... but they still bring a smile to your face when you push them down a flight of stairs.

This is what im up to at this point.
its not your standard build so it takes some extra time thinking and fabricating things like the motor mount and how to build so you could remove the motor if needed.

Well I cannot believe I forgot to take the picture of it in the jig with a arm bushing in both the front and rear mounts
with a shaft to mimic an armature and make sure there is no bind.
this is where I left off and needed a little break.

Its comming along bit by bit. I recived my order from PCH nice and fast.

In and out with long John to get the drive shaft done and next time the motor goes in it stays for a while. I cut the tires down to the hight of the ones from the model but im not going to norrow them untill a shakedown.
I did the front body mount and the rear is next.

I've gotten some nice soft tires for it and im hoping it will run without glue.
im starting with 16/62 =3.875 gearing so it is not to hard of a hit off the line and I think Lil John should have plenty of torque.

Weight distribution feels really good 4 wheel drive and the drop arm, I think will be a great combination with Little John.

Nice Job Joe, and congrats for getting to this build so quickly - I'd still be thinking about it!

I'm not that familiar with the gearing on can type motors: does it need something that high? (as opposed to the 2.5:1 or so on the padlocks). Especially if it's got as much torque as we assume, should be able to lower it to 3:1 or so.

Its got tall tires and I think its a good starting point. S16D close to that ratio with inlines some times higher.
Time will tell when I get to try her out.
we'll see if it runs out of breath before the finish line. I could always change it.

So both body mounts complete and this is the stance. A bit high but the olny choice I have wirh the tall tires all around and I wanted the rear to sit the same as the front and not lower.
all in all not bad.

It lives !
Today I mounted the motor and set up the drive line and fired it up on 6 volts 4 D battery's to get an idea if everything is okay. It was surprisingly smooth so I broke it in at 5 volts on the power pack for a few.

Kind of a special moment when I was setting up the gear mesh on the second side and the tires on the other side were moving. Somthing I've never experienced before.

The tires I used are just for this test because I want to round off the edges on the set I'm going to use.

Not bad for the first runs, the first few were in the two second range and I didn't realize the rear drive shaft was slipping and thinking I was spinning tire I use glue a bit disappointed.

After inspection is when I realized the drive shaft was slipping so I had Sam Reesolder it for me as he was at the workbench at Slots A Lot and put it back on the track going a 1.7 at 25 miles per hour.

That was enough I wanted to take it home and clean off the tires and maybe true them down a little bit since I think there was too much tire on the car.

The car leaves the line very nicely without the wheelie bar.

I think I will have to try to find a 17 tooth gear because the car was running out of steam about three quarter track.

This thread is too cool, when the car is detailed and tuned you'll have a keeper for sure! Congrats Joe.

Try a set of .435 tires...or even a set of .300...if you can get the wheels to ride somewhere other than the normal glue strip down the track, the car will probably like skinnier tires. Are you planning this for a bracket beast?

Yes a bracket car for sure and I'm sure going to make it look pretty.

Yes I plan on moving the tires outward just a bit more and narrowing them down.

Ill be happy at 1.5's.
